Erosion Control Speciality and Transportation Erosion Control Supervisor

We are your solution to you construction site pollution! ZGL specializes in SWMP documents and is your complete one stop shop for Erosion Control from the start of creating your stormwater plans to permitting, installations, maintenance, repairs and inspections.

    We are effective Transportation Erosion Control Supervisors (TECS) performing inspections while running through the Gauntlet checklist and updating the SWMP. As the eyes of the project on stormwater management during construction, our job is very important for achieving compliance with the applicable stormwater agencies for the project. Communication is also one of the key tools for our TECS to use with their construction team, PE, and superintendent. Communication allows the TECS to understand upcoming construction activities so they can be proactive and it allows the TECS to communicate to the construction team what is working and what is not working in the field, thus achieving stormwater compliance.
